Power Converter
Convert power between watts, kilowatts, horsepower, and megawatts. The form asks for a Value, a From unit, and a To unit, then shows the selected conversion plus the same input expressed in every supported unit.
Use this converter when comparing appliance loads, motor ratings, engine output, generator capacity, or solar equipment. If you are turning power into consumption or cost, pair the result with runtime in the time converter or estimate usage with the electricity cost calculator.
How to use this calculator
- Enter the power value.
- Choose watts, kilowatts, horsepower, or megawatts as the starting unit.
- Choose the unit you want back.
- Read the converted power and the reference list.
Conversion formula
The calculator converts the input to watts first, then divides by the target unit factor.
| Unit | Factor in watts |
|---|---|
| 1 W | 1 W |
| 1 kW | 1,000 W |
| 1 hp | 745.7 W |
| 1 MW | 1,000,000 W |
Worked example: 2 kW becomes 2 × 1,000 = 2,000 W. In horsepower, 2,000 ÷ 745.7 = 2.68 hp.
For a one-way shortcut, use the watts to horsepower calculator. For mechanical comparisons, the torque converter and force converter may also help.
